If 16oz kerosene makes 25 gallo d of 87 into 93, similar quantity of diesel should do a similar effect. I don't have te equipment to test, but anywhere from 92-94 octan
128 ounces in a gallon. 16 oz is 1/8 th of a gallon. So 1/8 to 25 gallons is 1:200 ratio, or .5%! Less than I thought, so if you add more then you are running fuel that does not burn completely untill well into the power stroke, acts as if the timing is way retarded.

Oil has been used as top lube, diesel was a top lube back when it had sulphur, I think the effect you are seeing is higher specific energy, diesel in small amounts below the actual octain affects which are to lower it is to reduce the vapor pressure or gasoline significantly.
The behaviors are quite complex so I am uncertain what you are really doing in that mix.
I will say that I have known (and others here as well) that diesel in small amounts does increase fuel economy in most gasoline engines (historic) but on modern engines that can tune themselves I can only image the affect is amplified.
The trouble with diesel which has an Octane eq of about 25 and parafin (kero) which has an octane rating eq of about 25-40 is that you never know the upper limit or what affects it may have long term on any given engine.
I will say however that modern "gasoline" as we call it already has diesel and kero heavy ends added in US fuel to cheapen it, add energy/economy, reduce vaporization and it has been like that for at least 22years I know of.
Get me an EXACT list of EXACT amounts of each component in modern gasoline and I will give you prize.
